Usage

To use CRPixellatedView, create a CRPixellatedView, configure and animate!

An example of making a CRPixellatedView:

CRPixellatedView *pixellatedView = [[CRPixellatedView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];  pixellatedView.image = [UIImage imageNamed:@"Image"];  [self.view addSubview:pixellatedView]; // Add to your view  [pixellatedView animate];

You can configure this settings, customizable example:

CRPixellatedView *pixellatedView = [[CRPixellatedView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];  pixellatedView.image = [UIImage imageNamed:@"Image"];  pixellatedView.pixelScale = 20.0f;  pixellatedView.animationDuration = 0.8f;  [self.view addSubview:pixellatedView]; // Add to your view  [pixellatedView animateWithCompletion:^(BOOL finished) {      NSLog(@"completed");  }];

Also, you can customize the animation effect using the reverse property:

CRPixellatedView *pixellatedView = [[CRPixellatedView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];  pixellatedView.image = [UIImage imageNamed:@"Image"];  pixellatedView.pixelScale = 20.0f;  pixellatedView.animationDuration = 0.8f;  pixellatedView.reverse = YES; // Reverse effect  [self.view addSubview:pixellatedView]; // Add to your view  [pixellatedView animateWithCompletion:^(BOOL finished) {      NSLog(@"completed");  }];

Examples

pixellatedView.reverse = YES; // Reverse effect
